<h2>Detailed Description</h2>
<p>The QStyleOptionViewItemV2 class is used to describe the parameters necessary for drawing a frame in Qt 4.2 or above.</p>
<p>QStyleOptionViewItemV2 inherits <a href="qstyleoptionviewitem.html">QStyleOptionViewItem</a>.</p>
<p>An instance of the QStyleOptionViewItemV2 class has <a href="qstyleoption.html#type-varx">type</a> <a href="qstyleoption.html#OptionType-enum">SO_ViewItem</a> and <a href="qstyleoption.html#version-var">version</a> 2. The type is used internally by <a href="qstyleoption.html">QStyleOption</a>, its subclasses, and <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>() to determine the type of style option. In general you do not need to worry about this unless you want to create your own <a href="qstyleoption.html">QStyleOption</a> subclass and your own styles. The version is used by <a href="qstyleoption.html">QStyleOption</a> subclasses to implement extensions without breaking compatibility. If you use <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>(), you normally don't need to check it.</p>
<p>See <a href="qstyleoptionframev2.html">QStyleOptionFrameV2</a>'s detailed description for a discussion of how to handle &quot;V2&quot; classes.</p>
<p>See also <a href="qstyleoptionviewitem.html">QStyleOptionViewItem</a> and <a href="qstyleoption.html">QStyleOption</a>.</p>

<h2>Member Type Documentation</h2>
<h3 class="fn"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionViewItemV2::StyleOptionVersion</h3>
<p>This enum is used to hold information about the version of the style option, and is defined for each <a href="qstyleoption.html">QStyleOption</a> subclass.</p>
